An Optimized Wideband Quarter-Wave Patch Antenna Design

This letter introduces a quarter-wave patch antenna design using a newly developed jumping genes evolutionary paradigm. The impedance bandwidth is improved by the use of a trapeziform patch with a similar U-slot. Both simulated and measured results have confirmed that 80% impedance bandwidth is achi...

Description
Summary:This letter introduces a quarter-wave patch antenna design using a newly developed jumping genes evolutionary paradigm. The impedance bandwidth is improved by the use of a trapeziform patch with a similar U-slot. Both simulated and measured results have confirmed that 80% impedance bandwidth is achievable using this design methodology.
